The bratty Baby singer dated Selena for two years before a messy split, but it looks like he is attempting to woo his former flame back – through the magic of Instagram.

Justin posted a collage of Selena attending the Vanity Fair Oscar afterparty to his page with the caption: "Most elegant princess in the world."

No prize for subtlety there, Biebs.

Selena did indeed look incredible at the bash, wearing a semi-sheer gold beaded gown with a plunging keyhole neckline.

However, such a romantic outburst is a rarity from Justin, who hasn't mentioned his ex in months.

The last time Selena made an appearance on his Instagram page was back in January when he posted a picture of the pair cuddling with the caption: "Love the way you look at me".

The popstars were also spotted riding Segways together in California, but Selena reportedly entered rehab for emotional trauma just a day later.

While Justin, who has been charged with driving under the influence after his now infamous Lamborghini drag race, seems to be still harbouring a crush for his former girlfriend, it looks like Selena has moved on.

The petite brunette sparked rumours of a romance with One Direction's Niall Horan after the pair were snapped by a fan on a date in London.

And the 21-year-old opened up about her "bad breakup" with her bad boy ex in Seventeen magazine.

The Wizards of Waverly Place star said: "I had always been the underdog secretly. I was on Disney when it was Miley [Cyrus], the Jonas Brothers, and Demi [Lovato]. I questioned the way I looked, acted, sang, and wrote.

"Then I turned 20, went through a really bad breakup, and realized I needed to have Come & Get It be amazing. I wanted it all to be me. 'I'm glad it's taken me this long to get where I am because now I am ready for it."

We hope Selena doesn't fall for these sickly sweet Instagram messages – Justin has hardly been sitting around waiting on his ex.

The star was caught with pretty blonde Chantel Jeffries on the night of his DUI arrest, as well as being linked to several other babes.
